Summary: Ref T7352. This is pretty straightforward. I renamed `phd.start-taskmasters` to `phd.taskmasters` for clarity.
Test Plan:
- Ran `phd start`, `phd start --autoscale-reserve 0.25`, `phd restart --autoscale-reserve 0.25`, etc.
- Examined PID file to see options were passed.
- I'm defaulting this off (0 reserve) and making it a flag rather than an option because it's a very advanced feature which is probably not useful outside of instancing.

Summary:
Ref T7352. This isn't wildly useful for us but seems generally reasonable, can be helpful with testing, and @hach-que has a use case for it.
The only reason we issue this warning is to prevent user error; you can still launch all the daemons with `phd launch` manually and daemons all use locks to protect critical regions.
Test Plan: Ran `phd start --force` a bunch, saw zillions of daemons.

Summary:
Fixes T5154. Currently, "phd stop" terminates daemons relatively abruptly (and other things do too, like killing them). This can leave them with long leases that won't expire any time soon. Normally this isn't a big deal, since it just means an email or an import takes a bit longer (often 2 hours, but up to 24 hours) to run. However:
- We've increased default lease durations a lot fairly recently -- the 2 hours used to be 15 minutes.
- Harbormaster and Drydock add new types of tasks which are more dependent on other tasks, so waiting 2 hours for something to free up can hold up more stuff in queue.
When `phd start` is run, we can be confident (at least, in normal circumstances) that leases are safe to free, since we do a check. This undoes any damage done by abrupt stops in "phd stop" or by users or systems killing stuff.
(It would be nice to make "phd stop" more graceful at some point, but we always have to deal with abrupt termination in some cases no matter how gentle "phd stop" is.)
One sort-of-questionable thing here is that we don't distinguish between tasks which had an active lease and tasks which had been released, since the system itself does not make a distiction. So, for example, if you have a task that retries 5 times and waits an hour between retries, you'll get a retry on every `phd start` now, and could exhaust them all in a few minutes if you cycle `phd start` aggressively. I think this is OK. In the future, we could try to distinguish between these types of tasks, and only free the ones with active leases.
Test Plan:
- Used `phd start` normally, saw it free leases.
- Used `phd start`, killed it real quick so no taskmasters spawned, ran it again an saw no leases freed.
- Used `phd start --keep-leases`.

Summary:
Ref T1670. Mostly, use PhutilArgumentParser. This breaks up the mismash of functional stuff and PhabriatorDaemonControl into proper argumentparser Workflows.
There are no functional changes, except that I removed the "pingConduit()" call prior to starting daemons, because I intend to remove all Conduit integration.
Test Plan:
- Ran `phd list`.
- Ran `phd status` (running daemons).
- Ran `phd status` (no running daemons).
- Ran `phd stop <pid>` (dead task).
- Ran `phd stop <pid>` (live task).
- Ran `phd stop zebra` (invalid PID).
- Ran `phd stop 1` (bad PID).
- Ran `phd stop`.
- Ran `phd debug zebra` (no match).
- Ran `phd debug e` (ambiguous).
- Ran `phd debug task`.
- Ran `phd launch task`.
- Ran `phd launch 0 task` (invalid arg).
- Ran `phd launch 2 task`.
- Ran `phd help`.
- Ran `phd help list`.
- Ran `phd start`.
- Ran `phd restart`.
- Looked at Repositories (daemon running).
- Looked at Repositories (daemon not running).
